RADIATOR.

SPECIFICATION forming part of Letters Patent No. 443,531, dated December30, 1890.

Application filed March 29,- 1890. Serial No. 345,843. (No model.)

To aZZ whom it may concern:

Be it known that I, JESSE A. LOSEE, of the city of Titusville,in thecounty of Crawford and State ofPennsylvania, have invented certain newand useful Improvements in Radiators; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

My invention relates to an improvement in radiators, its object being toso construct a radiator that a large surface thereof will be exposed andthat the circulation of air over such surface shall not be retarded,but, on the contrary, shall be assisted.

A further object is to provide a radiator adapted to be heated by meansof steam, hot water, or otherwise, said radiator being constructed andarranged in such manner that air circulating over its surface shall bepermitted to expand as its temperature increases without in any mannerretarding the free circulation of the air.

lVith these objects in view the invention consists in a radiator eachsection of which is made wider at its top than at its bottom and thickerat its bottom at its top.

It further consists in a radiator having ribs or projections whichdiverge from bottom to top thereof; and the invention further consistsin certain novel features of construction and combinations andarrangements of parts, as hereinafter set forth, and pointed out in theclaim.

In the accompanying drawings, Figure 1 is an elevation of one section ofmy improved radiator. Fig. 2 is an edge view of several sections. Fig. 3is a bottom view of four sections. Fig. at is an elevation of onesection adapted to receive hot water. Fig. 5 illustrates plan views ofthe forms shown in Figs. 1 and 4.. Figs. 6, 7, 8, and 9 are views ofmodifications.

The radiator adapted to be heated by steam is built of any desirednumber of thin hollow sections A, connected at the bottoms by means ofthe usual right-hand nipples B, and held together at their tops by meansof a bolt 0, said bolt passing through all the sections and provided atone end with a head and at the other end with a nut; or, if desired,said bolt or rod C may be screw-threaded at both ends for the receptionof suitable nuts.

Each section of the radiator is provided with a series of preferablyhollow ribs or flanges a, running from the bottom to the top thereof.Now, should the ribs be arranged parallel with the vertical axis of thedevice or vertical, so that the spaces between them will be of the samewidth throughout, the air starting at the bottoms of the passages formedby these ribs will increase in temperature as it ascends andconsequently expand, such expansion tending to retard the rise of airbeneath it, and thus to retard the free circulation of air over thesurface, or, more correctly speaking, through'the channelsor fines onthe radiators. As the heating capacity of a radiator depends largelyupon the amount of air that can be brought in contact with itsheating-surfaces, if the free circulation of the air be retarded orinterfered with the heating capacity of the radiator will of course bediminished. Therefore, in order to correct this serious defect in theconstruction of radiators I construct the sections thereof as shown inthe drawingsnamely, each section is made, preferably, flat and wider atits top than at its bottom and thicker atits bottom than at its top. Theribs or flanges a are arranged on the opposing faces of each section anddiverge from the bottom of the section, thus producing a series ofpassages or channels wider at their upper than at their lower ends.

By producing channels or passages in the manner above described it willbe seen that the air as it rises and increases in temperature is givenspace in which to expand, thus permitting a free circulation of airthrough the channels or passages.

When it is desired to heat the radiator by means of hot water, the longbolt or rod 0 will be dispensed with and the several sections fastenedtogether at their lower ends by means of short bolts 5. In this case thenipples at the lower ends of the sections are dispensed with and intheir place aseries of perforated bosses c are made on the severalsections. The upper ends of the sections are connected together byrighthanded screw-threaded nipples cl. When the several sections of theradiator are in position and-tho nipples d in place, washers c, ofelastic material, are inserted between the bosses c and the bolts 1)tightened, thus making a close connection bctween the boss, one sectionwith the boss of the next adjacent section. tion a hot-water radiatorwill be produced which will be of simple construction, easy tomanufacture, and by bolting the sections together at the lower end thescreen or cover ordinarily placed on radiators of this class j will bedispensed with, thus decreasing the expense of manufacture and stillmaintaining the effectiveness of the radiator.

If desired, the ribs or flanges may be made on one face only of thesections of the radiator, as shown in Fig. 9. By this construction thecost of manufacture is matoria-lly lessened without in any degreeimpairing the effectiveness of the device.

liy this construci fits opposite faces with ribs diverging from the baseupwardly, substantially asset forth.

In testimony whereof I have signed this specification in the presence oftwo subscr1bing' witnesses.
